(Give a letter or symbol.) study to apply is called a(n) the particular group of participants studied. refers to the larger group to which a researcher makes inferences based onExplanation / Answer
56. Correct answer is B. Population parameters are the actual values. Sample statistics are used to make an inferences about the population parameters.
57. Correct answer is D. We use Greek letters for the population parameters.
58.
A is matched with 4.
B is matched with 3. Population parameters are the actual values of the mean, standardard deviation of the population of interest in a statistical research.
C is matched with 2. Descriptive statistic of a sample data is used to analyze the mean or standard deviation or kurtosis, and skewness. Last two are used to describe the shape of distribution of the data about its mean values.
D is matched with 1. Samples and sample data are selected randomly where random means each sample as well as the data points in each sample has an equal chance of getting selected.
59. Answer is outcomes. All the possible outcomes or events as a consequence or result ofanexperiment. For example there are two outcomes if we toss a coin,such the outcome 1 is head, and the second one is tail.
60. pi=0.5. While analyzing the proportion of the count data, we are interested in either one of this if it is favor of an event of interest or againt. But the hypothesized population parameter pi is equal to 0.5
